I'm of the mind that you should choose for yourself, it's not fair for me to say you absolutely should never attempt or what have you, especially from a hypocrite like me. What I will also say is that often times, if you're not completely set on dying, your SI will probably get in the way and you will likely give yourself a good bit of trauma that you have to work through on top of what you already have to process should you choose to recover. I've had flashbacks myself of past attempts and they can be quite visceral so my concern would be that if you did decide to do it, but don't "go all the way", you could potentially put yourself in a worse position physically and mentally than if you had just sought help to begin with.
I respect your decision, but I'd recommend seeking help first especially since it seems like there's SOME part of you that wants to live and recover. Whatever you choose I wish you peace.
